In php, after starting a session then redirecting, do I need to start a session again?

Question

So if I start a session on one page, then send information via $_SESSION should I put session_start() at the top of the new page?

For Example:

page1.php:

session_start();
# code makes $foo
$_SESSION["var"] = $foo;
header("LOCATION: page2.php");
die;

page2b.php:

$foo = $_SESSION["var"];
# code uses $foo somehow

Does page2.php need session_start.php at the beggining of it? Especially if the only way to access it was through a page that starts a session?

是的...在每个页面中您都应该开始一个会话
